It will probably return 0 (or maybe -1) on error.
It may or may not also fill in $php_errmessage (?) or whatever the
variable is called.
It should be documented at http://php.net/rename what error codes it returns.
If not, you could run some tests fairly easily.

It won't work, and you have suppressed the error message, so you won't
even know it didn't work.
Using @ like that is just a Bad Idea.
You need to write better software that handles error conditions and does
something reasonable about them.

Pretty much, but not to the point that it blindly returns whatever the C
'rename' returns, probably.
You could read the PHP source and find out :-)
